Radamel Falcao came on in the 67th minute to make his debut for Manchester United

Angel di Maria opened the scoring for Manchester United as they romped to a 4-0 victory at Old Trafford

He added: ‘I hope to be manager of the champions – if not this year then in my second or third year.’

Di Maria insisted he had meant to score his free-kick. ‘I’ve been practising during the week and done that in training so it wasn’ t a surprise,’ he said. ‘I’m very happy with my Old Trafford debut. I feel very much at home.’

QPR boss Harry Redknapp questioned the quality of United’s defence and whether it will be good enough to repel the likes of Chelsea. ‘They have plenty up front,’ said Redknapp.

‘Whether they can cope with the forwards Chelsea have, that will be another game.’
